Moltres, Bird of Malevolence Winged Beast/Xyz/Effect/DARK/Rank 4 ATK 2200/DEF 1600 2 Level 4 monsters When this card is Xyz Summoned: Inflict 300 damage to your opponent for each Winged Beast monster in your GY, then this card gains ATK equal to the damage inflicted, until the end of this turn
"Disaster, Dragon Ruler of All Apocalypses" is the in-archetype finisher, potentially banishing all monsters on the opponent's field and Graveyard, while gaining 4600 ATK and becoming unaffected when all six Level/Rank 7 "Dragon Rulers" are attached as material
Id really want to leverage either the token or lifegain before playing this, but I dont mind it as a very flexible option
Most importantly, in a 75% deck, I want to steal their creatures and Blue lets me do that way better than Red
It's kinda like a sideboard card since its effectiveness is largely dependent on your opponents' actions
Then you need two copies of Myr Retriever, a rather forgettable card that lets you bring back another artifact card from your graveyard to your hand
